I use OMV from 2.x till atm.
My NAS configuration: AMD C60 + 8GB RAM + 4x2TB (RAID5) + 2x4TB(mirror)+SSD_32GB(system)+Gigabit ethernet
1 week ago I was upgrade my NAS from latest OMV 4 to OMV5.4.2 for get posiibillity to get updates.
In my home net live several devices with windows 7, android and with linux onboard.
After upgrade process samba speed was decreased. Write speed was before upgrading: 60-70MB/s, after 7-10MB/s, reading speed was 70-90MB/s, after 12-17MB/s
Any my changes in special options in samba/CIFS setup in OMV have no success. Differents speed after changes +/-2MB/s
O'cource before maked changes in special options I was read topics about samba speed tuning here, but it have no results.
Yesterday I was reinstall OMV5.4.2 on my NAS. And Samba speed stay so slow.
Please heeeeeelp, I think it can linked with samba version, but I possible have mistake with that. I have no any changes in my net, only OMV version changed.
